LAMP: Learning a Motion Policy to Repeatedly Navigate in an Uncertain Environment
نویسندگان
چکیده
Mobile robots are often tasked with repeatedly navigating through an environment whose traversability changes over time. These may exhibit some hidden structure, which can be learned. Many studies consider reactive algorithms for online planning, however, these do not take advantage of the past executions navigation task future tasks. In this article, we formalize problem minimizing total expected cost to perform multiple start-to-goal tasks on a roadmap by introducing learned planning problem. We propose method that captures information from learn motion policy handle obstacles robot has seen before. LAMP framework, integrates generated existing stack. Finally, extensive set experiments in simulated and real-world environments show proposed outperforms state-of-the-art 10% 40% terms time travel start goal. also evaluate robustness presence localization mapping errors real robot.

AGE REPLACEMENT POLICY IN UNCERTAIN ENVIRONMENT
Age replacement policy is concerned with finding an optional time tominimize the cost, at which time the unit is replaced even if itdoes not fail. So far, age replacement policy involving random agehas been proposed. This paper will assume the age of the unit is anuncertain variable, and find the optimal time to replace the unit.

متن کاملAn automated time and hand motion analysis based on planar motion capture extended to a virtual environment
In the context of industrial engineering, the predetermined time systems (PTS) play an important role in workplaces because inefficiencies are found in assembly processes that require manual manipulations. In this study, an approach is proposed with the aim to analyze time and motions in a manual process using a capture motion system embedded to a virtual environment. Capture motion system trac...
